A mobile hotspot is a physical site that provides Internet access through a Wireless Local Area Network (WLAN) using a router linked by an Internet Service Provider (I.S.P.). Mobile Hotspots mostly use Wi-Fi technology. Persons who wish to browse the internet can use a laptop, PC, Smartphone, tablet computers and other compliant devices to access the wireless internet connection. These devises come with a built-in Wi-Fi feature that enables owners to take advantage of the hotspot which is normally offered for free.

Security Concerns
Privacy and data security is a serious concern in regard to the use of mobile hotspots. The safest way when accessing the internet over a mobile hotspot bearing unknown security features, is using the end-to-end encryption. Examples of remarkably strong end-to-end encryption protocols are SSH and HTTPS.

Free Hotspots
Open public connection is the easiest way to set up a free mobile hotspot. All that is required in this is a Wi-Fi router. Owners of private wireless routers can turn off their validation requirements to open their connection and enable all internet users in range to access it.

Closed Public Hotspots
Closed public networks employ a Hot Spot Management Systems to manage access to the hotspots. This software runs on the Wi-Fi router itself or a peripheral computer enabling operators to permit only specific users to access the hotspot.

Commercial Hotspots
Many public establishments allow their hotspot access for a commission or a monthly fee. Users of a commercial ISP can access other ISP’s hotspots with roaming service. This can either be for free or at extra fees.

Software hotspots
Most Wi-Fi adapters built into computers and mobile devices have the functionality to act as private hotspots. This form of bridging is known as tethering. Computer hardware manufacturers can include this feature in Wi-Fi enabled devices.

Among the best companies that offer hotspot services is FreedomPop. It is based in Los Angeles, California. The tech company offers wireless data text and voice services for Sprint and Clearwire. It also sells tablets, mobile phones and other devices for use with their service. FreedomPop was founded by Steven Sesar and Stephen Stokols.

Its services are designed for internet “light users” and its paid options include unlimited text and talk with an option to include high-speed data. Its services are only available in certain locations. FreedomPop charges no active status fee for its new users. The company has been acclaimed for engineering the “Wi-Fi” technology. The technology enables users to send texts and make calls primarily using Wi-Fi networks when available.
